The most interesting thing that was covered is that when we were making lunar landings, we brought a couple of seismographs and placed them. Then, on a subsequent mission, the booster module that lifted the lander off of the moon was slammed down onto the surface of the moon. And, the result was that the moon resonated like a bell for 3 hours.

This is documented by NASA.

It is also well documented that while the moon's surface rocks are of the same stuff found here on earth, the moon's mass is much much less dense than the earth.

Some scientists have speculated that the moon is actually hollow - with a crust of 20-30 miles all around. Weird.

The other interesting thing pointed-out is that the moons's existence - it's origin is still not explained. Apparently the theory that it split-off from the earth has been disproven. And the other theory that it was "captured" also does not make sense. The moon has also been shown to actually be older than the earth itself..... also weird.

In addition, it has a tidal orbit - with the same side of the moon always facing the earth, and an orbit that stabilizes the earth's weather. Further, the moon is 1/400th the size of the sun and is positioned such that when it eclipses the sun, it exactly covers the sun as seen from earth - no more, no less. Again, very weird.

There were other ideas postulated - but they venture into the "conspiracy" side of things, so I won't go there. Everything I just mentioned is fact or scientific theory.

But it definitely makes you wonder.
